Deed Restriction / Land Use Covenant:

[VIEW COVENANT]   1/19/2007  For some strange reason, the state website does not list the site management requirements but if you click on the View Covenant you can read what is required, this is a deed restriction.

1.2. Raychem Corporation, the Covenantor’s predecessor, manufactured hightechnology plastic and electrical insulation products. It also engaged in management of hazardous waste pursuant to a hazardous waste facility permit issued by the California Department of Health Services, the predecessor agency of the Department. The hazardous waste facility permit allowed Raychem Corporation to operate a wastewater treatment system, a hazardous waste storage yard and a potassium ferrocyanide tank farm. On January 9, 1997, the Department approved the closure activities of the aboveground portions of these hazardous waste management units. Raychem Corporation proceeded with corrective action under the Department’s oversight to address the release of hazardous waste in soil and groundwater. Raychem merged with the Covenantor in 1999. The Covenantor has conducted corrective action at the Property under the Department’s oversight, including removal of contaminated soil, installation of an engineered multi-media cap over an area of subsurface contamination and groundwater monitoring.

Media silent as Navy digs 1,280 radiological objects from Treasure Island

by Carol Harvey San Francisco Bay View; National Black Newspaper October 12, 2018

“In 2014, Don Wadsworth, radiation specialist, a Navy subcontractor and now whistleblower, told NBC Bay Area We Investigate reporter Vicki Nguyen that an object the Navy photographed at 1101 Bigelow Court was a million times above the EPA limits for human toleration. However, in its 2014 Historical Radiological Assessment Supplemental Technical Memorandum (HRASTM), Figure 10, the Navy documents only this photograph of one radioactive object at 1101 Bigelow Court. Despite the Navy’s disclaimer, imagine this radioactive object multiplied 1,280 times. That is the total number of radiological objects Treasure Island Environmental Project Manager cited in March 2018 that the Navy located between 2006 and 2018. At the Hunters Point Shipyard, a single “deck marker” like this one is slowing down or halting a $8 billion development.“

“At the March 2018 Treasure Island Restoration Advisory Board meeting, remediation project manager Dave Clark “recollected” that, between 2006 and 2016, the Navy unearthed 1,280 radiological objects, one for every two residents.”

Article contains many videos relating to the disaster, the last video in particular shows the radioactive lake created in the cleanup and the signs by the Navy warning of the radioactive site.
